Something "nice" happened to Inmichess. By putting everything I heard from in, I also put some bugs into my program. Although it is fast, has a nice evaluation and all kind of stuff, it played sometimes really strange. In Tschoops summer Tournament, it got 4 points in eleven rounds. I looked to change the evaluation function to play better, most the pawn evaluation... but nothing, really nothing changed. I got angry and set some variables incredible high and ... nothing happened. Some Nights later, I found one variable set to 1 instead to zero. This variable disabled all (really all!) pawn evaluation in the middle game. The really strange thing is, that Inmichess with this bug did not really play bad. There were some nice games and I, on the first look, never thought, that there is no pawn evaluation at all. When I fixed the bug, I thought, Inmichess now will play "much" stronger. But the effect was about 100 Elo at all. (estimated by auto232 games) Maybe evaluation is not so important, as I thought (since the bugfix, my program is much slower), or the pawn evaluation is silly (i dont think so) or there are other strange bugs.
